Milk and water are in the ratio of 3:2 in a mixture of 80 litres. How ...
Given information:

- Ratio of milk to water in a mixture = 3:2
- Total mixture = 80 litres

To find:

- Amount of water to be added to make the ratio of milk to water equal to 2:3

Solution:

Let's assume that the amount of milk in the mixture is 3x and the amount of water is 2x.

According to the given ratio,

- 3x + 2x = 80
- 5x = 80
- x = 16

So, the amount of milk in the mixture = 3x = 3 × 16 = 48 litres

And the amount of water in the mixture = 2x = 2 × 16 = 32 litres

Now, we need to add some water to the mixture to make the ratio of milk to water equal to 2:3.

Let's assume that we need to add y litres of water.

After adding y litres of water, the total amount of water in the mixture will be 32 + y litres.

And the total amount of milk in the mixture will remain the same, i.e., 48 litres.

So, the new ratio of milk to water will be:

- Milk: 48
- Water: 32 + y

This ratio should be equal to 2:3.

Therefore,

- Milk/Water = 2/3
- 48/(32+y) = 2/3
- 144 = 2(32+y)
- 144 = 64 + 2y
- 2y = 80
- y = 40

Therefore, we need to add 40 litres of water to the mixture to make the ratio of milk to water equal to 2:3.

Hence, the correct answer is option B, i.e., 40 litres.
